Winchester 70 Classic .375 H&H stocks?

I need some help and suggestions on finding a new stock to replace my old injection molded piece that came on my Winchester model 70 Classic SS .375 H&H with the 2 piece floor plate. I'd like to keep a composite stock on this to use in foul weather since this is a stainless rifle. I've used this forums search engine and came up without any results. I have checked at Stockys and a few other places also. My main concern is the barrel channel being large enough in the factory sporter magnum stocks to fit the .375 H&H factory barrel contour, as it appears larger than say, a std. 300 win mag contour. Thanks for any help offered!! Tim
